Construction and Application of Multivariate Linear Regression Model on Road Cost

Abstract:

This paper analyzes the impact factor, combined with practical engineering experience to extract the main influencing factors, and based on research data on the major beneficial factor for statistical analysis to understand trends from the road cost; selection of multiple linear regression model, the unit cost per lane kilometer as the dependent variable, the cost factor as independent variables, the cost estimate to build the macro-factor model and the cost of each grade highway microeconomic factors estimation model.
